How do I setup a Shooting Trigger to make an Animation play on a Platform?

My Unity Project is a puzzle game that relies on shooting batteries to then turn on moving platforms. This puzzle mechanic can be used to navigate through a series of moving platforms via multiple batteries.

1. I have setup the animations on my platform to trigger, I just need to actually make the trigger happen when I shoot the battery. I have code that turns the battery 'on', it just doesn't affect anything when on yet.

2. So my problem is: I don't know how to code an event for when I turn the battery on, and how that will then turn the moving platform animation on.

3. I can think out the steps, but I cannot use the language correctly to make those steps happen.

4. Thank you so much for any help! I hope you have a great day!
